Having such freedom is repeatedly helpful and additionally important, but collaborating on a project with totally different developers can before long need a group of writing style guidelines. vital to grasp here is that regardless of that coding style you pick, outline it well and follow it when adding new code. Reading code with consistent coding style matters.

Useful tools


Clang-Format is a set of tools that are built on top of LibFormat that are very useful to format your C code to a predefined coding style.

The main tool is clang-format. You initially create a YAML file called .clang-formatin your project root directory with definitions of how formatting should be done.
